You have some sunglasses from customers they broke apart this is all just plastic. They broke apart right here so they're not fitting in there just coming right out. So I drilled a way a hole almost all the way through and I'm going to put a little bit of magic in there and that magic is a paper clip that I just cut apart. Go all the way through and make sure it's in there all the way. Go all the way in there nice and snug no there we go. Now that pin is probably going to come out so I'm going to put a stopper in there and the stopper is I just welded two pieces of the paper clip together and I'm going to weld it here now. Now there we go. You're using just low parameters about 200 volts, 4 milliseconds, 0.6 millimeter beam size. Okay so now that is in there. I'm now going to move up and down and the pin won't come out. There you go save the customer his sunglasses. They can wear them another day.
